If you do peritoneal dialysis (PD), you may be able to take in slightly more phosphorus, potassium, sodium and fluid than if you did hemodialysis. You will also need to eat more protein. This is because PD works all day and night to take waste and fluid out of your blood. This keeps the waste and fluid from building up in your blood like it does between hemodialysis treatments. If you do PD, talk to your dietitian about making a diet plan that is right for you.
